Question to the Department for Transport:
To ask Her Majesty's Government what methodology they use to estimate the costs of high-speed rail projects in the UK.
The Department for Transport looks to its Arm’s Length Body, HS2 Ltd and its consultants to estimate the cost of High-Speed Rail Projects in the UK, including the Rail Method of Measurement (RMM) and Civil Engineering Standard Method of Measurement (CESMM). The estimates are tested through benchmarking both nationally and internationally and are ultimately validated through the contracted prices HS2 Ltd secures with suppliers.
